Question

The vapour pressureof water is 12.3 kpa at 300 k .Calculate the vapour pressure of 1mol of solution of a solute

Answer 1

Answer:

Hey dear,,,

The vapour pressure of water is 12.3 kPa at 300 K. Calculate vapour pressure of 1 molal solution of a non-volatile solute in it. 1 molal solution means 1 mol of the solute is present in 1000 g of the solvent (water). Hence, the vapour pressure of the solution is 12.08 kPa.
